Serial No. 440,451.

:This invention relates to a printers chase locking device which is of utility in making a very rapid locking of set-ups oftype or the like in a chase. Usually the set-ups are of B substantially uniform size and :a number of them, usually four, may be located in the chase and by a single operation all four of the set-ups securely locked inplace by a single manual operation. Theinvention is particu- 1 larly useful in connection with printing the pages of directories,such as telephone directories, though inno sense limited thereto as books of any size similar to that of directories mayhave set-ups for the pages thereof, and thus have availability for the use of the chase locking apparatus of our invention.

@ It is an object and purpose ofthe present invention to provide a chase locking apparatus of the type noted whereby rapid change 0 of set-ups in a chase and locking of the new set-ups in place is attained. For instance, in printing a telephone directory, a chase carrying and having locked therein the type set-ups for four ofthe pages may be usedin printing until the entire run of such pages of the directory is completed, whereuponthe set-ups for four other pages may be put in the chase, the first four being quickly released and removed and the others substituted and almost instantly locking in the chase, thereby saving agreat dealoftime with a consequent economy in printing. Many other objects and purposes subsidiary to the primary obj ectstated will be apparent and may be understood from the following description taken in connection with the accompanying drawing, in which,

Fig. 1 isa plan view of a chase having a plurality of page set-ups locked therein using my invention, and

Fig. 2 is a fragmentary enlarged plan illustrating the manner in which the locking mechanism is operated.

Like reference characters refer to like parts in the different figures of the drawing.

The printers chase may be made of any suitablematerial and is of rectangular form having parallel sides 1 spaced from each other and parallelspaced ends 2. While in practice the chase is provided with a sheet metal bottom preferably the constructive details of the chase form no part of and import no limitation upon the present invention. 1 i

Substantially midway between the ends of the chase and extending across the same are dividing bars 3 the adjacent ends of which are spaced apartand are connected together by an overlying metal plate 4 through which a circular opening is made. At each corner of the chase filler blocks 5 are located extending toward each other from the sides of the chase, at their inner end portions being reduced in thickness as indicated at 5a, the adjacent ends of the parts 5a being parallel to each other and serving as guides for parts of the locking mechanism as will hereafter appear. A flat metal bar 6 is secured at the upper sides of and inner edges of the blocks 5, extending beyond said inner edges and having a length equal substantially to the distance between the sides 1 of the chase as fully shown at the upper part of Fig. 1.

The type set-ups, which are inked to give the impressions to paper in printing, are of rectangular form as indicated at 7 The ends of the set-ups 7 bear against bars 8 and 9, the bars 8 coming against the cross bars 3 previously described, while the inner side edges of the set-ups 7 bear against other flat bars 10 located lengthwise of the chase parallel to each other but spaced a distance apart.

The bars 9 at the outer ends of the set-ups 7 come against bars 11, as shown in Fig. 1, which at their outer edges are formed with spaced apart inclines 12; and the inner side bars 10 bear against somewhat similar bars 13 having flat sides against which the bars 10 seat and at their inner sides being formed with a plurality of spaced apart inclines 14 as shown. The bars 13, having the inclines 14, are likewise a distance apart from each other and between each of the pairs of bars 13, one pair above and the other pair below the cross members 3, a locking bar 15 is mounted which is provided with complementary spaced inclines to bear against the inclinesl on the bars 13 whereby, on movement of the bars 15 lengthwise toward each other, the bars 13 are wedged apart and thereby force the set-ups 7 toward the sides 1 of the chase and into very firm engagement therewith.

The outer ends of the bars are provided 5 with extensions'16 to each ofvwhich a head 17 is permanently secured. The heads 'l? are located between the ends of the parts 5a 1 previously described which serve as guides for the" heads in'their move1nents. Levers at each side ther eof,'and extend outwardly therefrom andat an angle to vthe ends o the chase having plvotal connections at their outer ends to bars 19. The bars19 at their outer sides have a flat sliding engagement against the inner sides of the blocks 5and at ably-connected thereto'threading onto the 'threadedinne'rrend 21 of a bar 15. The operating members "22 pass by each other and at their adjacent sides are provided each with a series of rack teeth 23 which pass underneath the opening in the plate l. "A key 24- having a pinion like head adapted to be passed through the openingin the plate 4 and engage with the teeth of both racks 23 whereby, on turning the key in-one direction, the two bars 15 maybe drawn simultaneously lengthwiseptoward each other producing a simultaneous outward movement to all of the bars 19 and the locking movement of all the locking bars 15 and 19 occurs simultaneously; and evidently on turning the key in the opposite direction therelease of the locking appliance is instantly effected. The plates 6 serve as guides and holdersover the locking bars 19' and also pass over the links and the ends 16 of the bars 15, keeping them from disengagement from the chase.

shown and described as used with a printers chase it is conceived that it may be used equally well with a printers galley and it is intended that the word Fchase wherever used in the claims shall be considered :as of sufficient scope to include a galley or any other analogousframe or receiver of a type set-up.

The construction is very practical and has so proved in use. With it the release of type 'set ups, a plurality of them in a chase, and the replacement thereof by others with substantially instant locking of the same in the chase is very effectively accomplished. The invention is defined in the appended claims and is to be considered comprehensive of all therefrom. 7
